# The Bulk SOAP API stops working

Calls to /Api/* on Microsoft Advertising Bulk API stop working on January 31, 2027.

On January 31, 2027, the Bulk SOAP API stops working. Calls to endpoints matching /Api/* will fail after this date because the SOAP API undergoes full deprecation.

## What to use instead

Migrate by calling the Bulk REST API instead. Alternatively, upgrade the .NET or Java SDK to version 13.0.22 or later, or switch from the Python or PHP bingads package to msads.

## Microsoft Advertising Bulk API's words

> The SOAP API is scheduled for full deprecation on January 31, 2027. We recommend migrating to REST as soon as possible to ensure a smooth transition and avoid disruption when SOAP is deprecated.
